IPC: H01J35/28
Filed: 1990-04-27
Abstract: PURPOSE:To increase electron beam dose able to radiate to a target and the output of x-ray generation by rotating a target on a rotary shaft and at the same time moving the target in the rotary shaft direction to extend the length of a focus track of electron beam. CONSTITUTION:A target 21 is fixed in a rotary shaft 22 and made movable in the rotary shaft direction by electromagnets 26a, 26b for floating it in the rotary shaft direction. The focusing track of electron beam radiated to the target 21 from a cathode 7 is extended by controlling the movement of the target 21 in the rotary shaft direction as well as the rotation of the target. In this case, the control of the movement of the target 21 in the rotary shaft direction means repeated reciprocal moving control of the target so as to move the focusing position of the electron beam on the target 21 from one end of the target 21 to the other lend. Consequently, electron beam dose able to radiate to the target is increased and thus output of x-ray generation is increased.

Abstract: PURPOSE:To refine Al by a simple work and with high refining efficiency, by exhausting gas from the center part of the lower surface of a rotary body in liquid phase existing in the vicinity of a solidification interface, and rotating the rotary body, when solidifying molten Al from the lower part. CONSTITUTION:A graphite crucible 55 into which molten Al 56 to be refined has been put is placed in an electric furnace 51, a rotary body 31 is placed in the crucible 55, and the Al 56 is cooled from the lower part by a chill 52. As a result, nuclear generation occurs on the bottom surface of the crucible 55, and instaneously a solidification interface is formed. Subsequently, the rotary body 31 is positioned at a position where the lower surface of the rotary body 31 is opposed to the solidification interface at some distance against the interface, and gas is exhausted from a through-hole through a gas feed passage 5 of a rotary shaft 2. This becomes fine bubbles by a rotation of the rotary body 31, diffuses and mixes impurities in an impurity concentration layer formed in the vicinity of the solidification interface throughout the liquid phase, and gives high purity Al.

Filed: 1984-05-31
Abstract: PURPOSE:To obtain a power source having high universality by selectively varying the pattern distribution of a slit shape of a rotary cylinder or a photoelectric converter array which receives emitted light from the rotary cylinder. CONSTITUTION:A photoelectric conversion power source has a stationary cylinder 12 arranged with photoelectric converters 15, and a rotary cylinder 13 provided with slits 16. The arraying pitch (p) of the slits 16 is double of the bottom side width (w) of the slits, and the shape of the slit is formed in a sinusoidal wave pattern having a period 2w. The converters 15 are formed of many elements 15 connected in cascade in response to the slit pitch P, and connected at both ends with upper and lower output 31 lines 7. Thus, the emitted light fed through the slits 16 is emitted to the converters 15, and sinusoidal alternating voltage is obtained from an output terminal 1. An alternating voltage of arbitrary waveform in addition to the sinusoidal wave can be obtained by arbitrarily converting the pattern of the converters 15 or the slits 16 themselves.
